Sad, but then why did he tried to make him like his past self (android) this is no sense. Except if it means that he love his son and tried to make him able to have a maximum of opportunities but didn't knew how to take care of him emotionally.
You are all right the art droped a lot, yes the chapter are faster but isnt it better to have slow but good chapters. Because if we wanted just the story we would have gone for the novel
At first i tought he would forfeit to give humanity a free win, then he do better than this :"if you can't beat them join them" 😂
In this case he just want to save them (not all gods wants humanity to loose some are neutral)
You all forget one this he can get the 99th boss skill if he go there an then return to take the godness reward by returning in time. So it is definitly op. If he hadn't this skill yeah maybe it would be a bad reward. The only difficulty is that he can't die before killing the top 10
